Calculus is the mathematical study of change in the ways of geometrical shapes and algebra for the simplification of arithmetic calculation. Ideally, there are two major branches of calculus, namely integral calculus and differential calculus.
There are two major branches of calculus, namely integral calculus and differential calculus. Here integral calculus is the gathering of quantities, and areas between or area under curve calculus. While differential calculus concerns instant rates of change and the slopes of curves.
Students will learn how these two branches are interlinked to form fundamental theorems of calculus under this section, as they use the basic concept of convergence of infinite series and sequences to a defined limit. Here the formula to calculate area between two curves calculus is explained in detail.
Ways of Finding the Area under a Curve Calculus
Here is an example to show how the area under curve calculus is calculated. Take a look!

In the above figure, one can assume the curve y=f(x) and its ordinates of the x-axis to be x=a and x=b. To understand how to find the area under the curve, students have to assess the area surrounded by the given curve and its ordinates show that x=a and x=b.
Here one can find the definite integral area under the curve. Taking a random strip of height as Y and width as dx. In the figure above, dA is assumed to be the area.
Now the dA area of the strip is provided with a dx while a point in the curve that is y is represented through f(x). The strip areas between curves calculus can also be termed as an elementary area between the x-axis. And the curve is located between x=a and x=b. To find the total is bounded by this curve, one has to consider there is an infinite number of strips. These strips start from x=b to x=a. Adding an elementary area between given strips in the region PQRSP helps find the total area needed.

To calculate the area of the curve by integration or under the curve, let’s take x=g(y). Here between the lines y=c and y=d lies y-axis. This can be given by the formula A=∫cdxdy=∫cdg(y)dy.
One has to keep in mind that there is a horizontal strip like the image above. If a curve lies underneath the x-axis where f(x) is less than zero then similar steps will give the needed area under the curve. This will be negative in value as it lies under x-axis and between x=a and x=b.
It is suggested to take an absolute value of an area without the .|∫abf(x)dx| sign to find the area under curve calculus.
To determine the calculus 2 area between curves, one has to take an example where the area between y=g(x) y=g(x) and y=f(x) y=f(x) is interval [a,b]. Let’s take an assumption that f(x) is less than equal to g(x).
To find the exact value, we have to use the formula A=∫dcf(y)−g(y)dy. It is vital to remember that the first function value is larger. It is smarter to use the term formulas to show that area will be larger minus smaller function.
Apart from these formulas, students need to practice calculation of area bounded by a curve and a line for a better score in boards. Every student desires quality practice material to excel in competitive exams.
